Recent advances on the development of a 4J latticematched dilute nitride solar cell for terrestrial and space applications are described. Modeling of the solar cell is carried out using a drift-diffusion model and material parameters extracted from ad hoc electro-optical characterization resulting in an efficiency prediction of 47% for concentrations of 1000 suns AM1.5d G173 spectrum and 33% for 1x AM0. First experimental solar cell results of a dual-junction GaNAsSb/Ge solar cell and a triple-junction GaInP/Ga(In)As/GaNAsSb components of the full 4-Junction are shown.
